Frequency of female worms as a function of the proportion of degenerating microfilariae in their uteri.

<p>These frequencies were plotted before and 80 days after ivermectin treatment for the control and frequently ( = multiply) treated groups. The proportion of degenerating microfilariae was assessed from 15 µl of the homogenized suspension resulting from the crushing of each female worm.</p

Composition of the nodules and distribution of female worms according to their uterine contents.

<p>The evaluation of the uterine content was done from 15 µl of the homogenized suspension resulting from the crushing of each female worm. We expressed the numbers of embryos using this volume (15 µl) as arbitrary unit; sd: standard deviation; mf: microfilariae; max: maximum.</p

Mean number of embryos per female worm before and 80 days after ivermectin treatment.

<p>These data are presented separately for all female worms (a) and only for productive female worms (b) and are compared between the control and the frequently ( = multiply) treated groups. The mean number of embryos was assessed from 15 µl of the homogenized suspension resulting from the crushing of each female worm.</p

Distribution of female worms according to the density of oocytes in their uteri.

<p>A semi-quantitative approach was used to classify the density of oocytes into four categories: absence, rare (less than one PSC), few (1–10 oocytes PSC) and numerous (more than 10 oocytes PSC). The density of oocytes was assessed from 15 µl of the homogenized suspension resulting from the crushing of each female worm.</p
